It appears that Quickbooks is not taking enough Payg withheld from my employee is there a way I can change the amount taken so that he doesn't get a tax bill in June

Yes, there is a way to update the amounts taken in Pay-As-You-Go (PAYG), tdhy. I will elaborate on this process.

PAYG is calculated based on the employee's taxable earnings, pay schedule, and the details provided in their Tax File Declaration. For further guidance, you can visit the ATO's Tax Table or use the ATO's PAYG tax calculator, as QuickBooks adheres to the ATO's PAYG computation guidelines. Now, refer to the steps below on how to update the PAYG:

1. Open the pay run.
2. Click on the employee's name.
3. Choose Actions and Adjust PAYG.
4. Enter the PAYG amount and hit Save.
5. Verify the PAYG column to confirm if the amount is correct.
